IClaim. (01. 301-38) The invention relates to an auxiliary wheel and ofa kind for attachment to a vehicle wheel of the pneumatically tiredtype.

The primary object of the invention is the provision of a wheel of thischaracter, wherein the same can be conveniently and easily attached to avehicle wheel carrying a pneumatic tire so thatwhen the said tirebecomes deflated by puncture, blowout or otherwise the auxiliary wheelwill support the vehicle for the continued travel thereof without damageto the deflated tire and thus enabling the vehicle to reach a servicestation for the repair of the tire without running upon the saiddeflated tire.

Another object of the invention is the provision of a wheel of thischaracter, wherein the same includes complemental halves: Thus one halfmay be applied to a vehicle wheel at the upper half of the wheel, whenthe tire of the wheel is deflated, so that when the wheel is turned itwill be lifted off of the deflated tire and the other half applied inproper position so that the auxiliary wheel will afford traction in theservicing of the wheel until the damaged or deflated tire has beenconditioned for service.

A further object of the invention is the provision of an auxiliary wheelof this character, which is simple inits construction, thoroughly Ireliable and eflicient in its operation, readily and so easily appliedto and removed from'a vehicle wheel having a pneumatic tire, and isstrong, durable, and inexpensive to manufacture.

with these and other objects in view, the invention consists in thefeatures of construction,

35 combination and arrangement of parts as will be hereinafter morefully described, illustrated in r the accompanying drawings,which'disclose the preferred embodiment of the invention and pointed outin the claim hereunto appended.

40 In the accompanying drawings:

Figure 1 is a side elevation of a vehicle wheel showing the pneumatictire deflated and one half of the auxiliary wheel attached to thevehicle wheel.

45 Figure 2 is a view similar to Figure 1 showing the vehicle wheelshifted with the half of the auxiliary wheel sustaining said vehiclewheel elevated for the application of the other half of the auxiliarywheel thereto.

50 Figure 3 is a view similar to Figure2 showing the complemental halvesof the auxiliary wheel attached to the vehicle wheel.

Figure 4 is an enlarged vertical transverse sectional view through thevehicle wheel and the.

55 auxi ary wheel.

Figure 5' is a sectional view onvthe line 5-5 v of Figure 1.

Figure 6 is a fragmentary sectional view on the hue 6-6 of Figure 3.

Figure '1 is a fragmentary elevation of a mod 5 ified form of auxiliarywheel.

Figure 8 is a perspective view of the tool or implement used with theauxiliary wheel for the' application and removal of the same from avehicle wheel. 10

Similar reference characters indicate corre-' sponding parts throughoutthe several views in the drawings.

Referring to the drawings,particular1y Figures 1 to 6, inclusive, Adesignates generally 2. ve- 15 hicle wheel, in this instance of the wirespoke type having the hub 10, spokes II and felly l2, the spokes llbeing integrally joined with the hub and felly. The felly I2 is of thehollow or channeled construction for the demountable 20 mounting of thepneumatic tire l3 thereon, the latter being conventional in its make-up.

The auxiliary wheel for use with the vehicle wheel A comprisescomplemental halves B--B each being made from sheet metal and of half 25disk form having a flat center portion M with a bulged outer portion l5concentric thereto with a peripheral channeled felly l6 for the seatingtherein of a resilient tread ll. These halves B-B mate each other andwhen mated the perimeter of the same is of a diameter substantiallyequal to the diameter of the tire I3 at the tread thereof under normalinflation.

The ends of the felly portions N5 of the respective halves 3-3 are bentlaterally in the same direction as at l8. The bent ends l8 on one of thesections are extended inwardly with respect to the wheel, while the bentends l8 on the second or co-operating section are extended laterallyaway from said wheel so that the two ends of one of the sections canoverlap the two ends of the other section, when the sections areassociated.

For the fastening of the halves BB of the auxilary wheel in matedrelation and upon the vehicle wheel, A there are provided the turnbuckle clamps l9 and 20, respectively, the halves being formed withelongated slots 2| for the securing of the clamps in place to fasten thehalves B together and to the vehicle wheel. Y

The halves B have bent or struck therefrom clencher flanges 22 forengagingwith the side of the felly ll of the vehicle wheel A in thefastening of the halves to the latter.

In Figure '1 of the drawings there is shown a slight modificationwhereineach half of theauxiliarywheelhasnexttothefellyportion 23 thereof spacedradially slits 24 whichprovideresillencyinthesaidhalfCconcentricallywith relationtothecenter'portion InFigure8ofthedrawingsthereisshownanimplement 2G employed for the molmting anddemountingoftheauxiliarywheelandthisimplement afiords awrench 21 atoneendl so that theturnbucklesoftheclampsliandllcan be operated therebywhile 'the other end 28 of the implement or tool is for prying purposes.Intheamlicatimofthehalvesto thevehiclewheelAthisendIloftheimplementortoolisinsertablethmughahole provided ineachhalfBorC'forthepurpose offulcruming the toolonthevehicle wheel tellyorriml2andforcingtheflange22betweenthetireliandarlmflangeasshownini'lgured.

Inthe applicationoftheauxiliarywheel after the tire l3 becomes deflated,itiS t0 putonehalfBinplaceuponthewheelhand is done by locatingsuchhalf'at theuppermostportionofthewheehusingtheclamp l9 forthe holding ofsuch half in place until the wheehA has been turned a full halfrevolution whereupon the applied halt B elevates the wheel from theposition shown in Figure 1 to thatshown in Figure 20f the drawings.

'The clamp l9 thus applied is temporarily re reverselyangledendsofthenitv labor of the operator. or reversely angled ends on the sections of myshould be stated, provide one of the most important features of theinvention. One of the halves or sections B may be arranged on the wheelwith comparative ease, but when the wheel is turned to the positionsshown by Figures 2 and 3 of the drawings, the application of the secondsection B, by a single operator, would be a matter of difliculty werethe meeting edges of thesections straight throughout. The operator wouldbe forced to hold this section with one hand and grope with his otherhand to obtain the necessary tools and fastening means for securing thesections together and perhaps exert force upon the periphery of theunattached section, which might inflict injury thereto and which wouldalso add to the By employing the wings improvement, one of the sectionsB is attached to the wheel by'the central clamp l9 and the wheel isturned (by the engine of the machine) to the position shown by Figure 3.The second or detached section B is lifted by the operator and arrangedto have its angle ends contact with and glide over the angle ends of theattached section B. The unattached section will slide to proper positionwithout further han- I dling of the operator and it is then merelynecessary to apply the fastening means to the mafing sections B. a

What is claimed is:

An auxiliary wheel of the kind described,

complemental substantially half circular sections, each having a tellyat its outer periphery, tread pieces fitting said fellies, meansclamping'the sections in operative position upon a pneumatically tiredvehicle wheel, and inwardly and angularly disposed felly extensions onsaid sections for overlapping each other when the sections are upon thevehiclewheel. v
